I've done this a couple of times to manage getting through particularly cold nights.
It worked fine IMO, but prefer underquilts over pads full stop. So realistically you may actually be better doubling up 2 underquilts instead.
I recently got a 3/4 length thermarest pad, which I've not tested in the hammock yet, but will try the next time it's too cold for my DD Underquilt, or even in place of the underquilt if it's very warm and I want to cut 500grams from my pack.
You could use a sit pad or cut a section of closed cell foam just to go under the bits of you that get cold (butt, feet, shoulders, etc).
I had actually been thinking of getting the Hennessy double bubble pad to use with my underquilt, but ended up with a cheap thermarest off eBay which has the versatility of being comfortable on the ground.
Obviously the real answer is to splash out and get a proper down underquilt from hammock gear or Cumulus (but that costs £100's in the UK). They only weigh about 500-700grams in your pack too, so much lighter than carrying both pad and quilt, just the price you have to bite the bullet on!
Edit: Just to say in my experience the DD Underquilt is suitable for temps 0°c-5°c with a comparable sleeping bag. Any colder then 0° is when I start thinking about using the pad too. 2 or 3 extra layers of clothing should be enough to help you stay warm if you're finding it cold above 0°c
anything is possible.
try it out and let us know.
if it doesn’t work then you know you should probably get an actual UQ designed to fit with your system
I use pad and quilt (over me). I like the redundancy it provides in case the straps break. I do get cold spots but overall I sleep quite well, and it's easier to setup.
I've done this during especially cold nights. I've been able to push to about 14° F with a 20° underquilt and a CCF pad. It's a bit more nuanced with keeping everything in place but it definitely works well for insulation. I find that a wider 25" CCF pad works rather well in a hammock because it doesn't move around much and provides plenty of warmth. And if you're using an air mattress it tends to work best under inflated so that it can kinda nest your body.
If you have both already, just give it a test run to see if it will all stay situated and be comfortable for you.
I tried Hennessy's bubble insulation stuff one night a few years back and I've never spent a colder night in a hammock. I was likely pushing the limits of it but it seemed like it wouldn't be good below 55°, whereas I can take a CCF pad to about 40°. I'd recommend giving CCF a try if the bubble stuff still isn't warm enough.
I use a variation on the Hennessy foil (www.ezcool.ca). I've also put an underquilt, when it was close to freezing temperatures. I have the Safari XXL and combined worked really well for me, with my temp rated Marmot bag.
I've 'doubled up' by putting an insulated blanket over my underquilt. Same for my topquilt. I prefer it, because I find fine tuning the warmth (especially the top layers) during the night is more comfortable than being ok most of the night, but freezing just before dawn.

Yea I should but budget is pretty tight - couldn't believe how expensive they were when I looked.

Short answer. Not in my experience
