I've got a WM Sumerlite @32F, which has been rock solid for me in low 30's. I still use it as a top quilt for most of the 30-50F hikes in my hammock. I suspect the Versalite is a solid bag based on the performance of the lighter weight version.
I am a cold sleeper too. And I’m embarrassed to admit, I could afford a western mountaineering bag. It was 0°. And I’m 59 and I got the 6 foot six version. Giving me tons of down to snuggle into. I actually use this bag way more than just the winter and I’m always toasty warm.
Western Mountaineering, Feathered Friends or Marmot for bags. Enlightened Equipment, Hammock Gear or Katabatic for backpacking quilts. Not cheap but quality and comfortable.
I've been a quilt user for years, but if I were looking for sleeping bags, I would go with either Western Mountaineering or Feathered Friends. You absolutely get what you pay for with either brand. Awesome quality.
Good pad. Stick with that.
Edit: (I forgot about the Nemo eclipse. That's something to look at. I don't think they're ready to ship yet. I don't know that factually. I think they're officially going on sale in march. REI was doing pre-orders.)
Someone mentioned Western Mountaineering. That's the best. But they're expensive. I don't know if I'd recommend it for a beginner. I have one and it's totally worth it. If you know you're going to be out there, then maybe eventually you want to make that investment.
In general about sleeping bags look at the EN or ISO Comfort rating. If they don't have that, you probably don't want it. That's an incorrect statement. Because even some top brands don't necessarily publish that for certain bags. In which case you just really need to look deeper into that bag. To give you a specific example, Western Mountaineering has EN number is published on a chart under their faqs. But that only goes down to their bags that are about zero rated and above. That doesn't mean that they're cold weather bags are crap. The exact opposite actually. But a lot of budget brands are throwing a temperature rating on there that may be more related to the extreme limit number which is survivability and you'll just be cold. If you want to look at the difference between the comfort, limit, and extreme limit rating, you can. But just stick with comfort. Maybe build in an extra 10° from what you actually expect to sleep in.
That's a heavy tent. You can save a lot of weight there. Let me offer a specific alternative. Durston Xmid 2. It's a trekking pole tent. If you wanted to try trekking poles, this is a great way to save weight. If you don't want to use trekking poles, Durston sells ZFlicks poles. You'll still be significantly lighter than the Half dome 2.

Naturehike is a budget brand with tents you can look at to see if one would work for you. You'd save money. And probably can come out a fair amount lighter.
Check out r/ultralight. I'm not saying you should go full ultralight. But if you're going to be backpacking, save weight where you can.
Western Mountaineering has sleeping bags that you can order with one being right zip and one being left zip. And then you just zip them together.
But I'm going to be honest. I don't know your friends and family. That's not something I would put on a wedding registry. And I don't mean I wouldn't put sleeping bags on there. I wouldn't put Western Mountaineering on there because it's so freaking expensive. I have one. I bought it for myself. I'm okay with that. I'm just saying I wouldn't ask anybody else any kind of obligated way like a wedding registry to spend that much money on me.
What I'm seeing from the comments is that there are probably other brands that can do this. I just don't have a more affordable specific recommendation. So a little research might turn up a good result. I know a lot of brands are going to use zippers from similar suppliers. But my sort of guess is that you'll be better off finding a brand where they specifically state their bags zip together and then get two from them that you know are compatible.
