Underfloor heating questions...

I'm about the rip up the floorboards in my hallway and downstairs bathroom (which runs off the hallway), replace with a ply subfloor and fit a Karndean vinyl floor on top that runs through both.

There's a large radiator in the hall and a small towel one in the bathroom. I want to get rid of both in an ideal world, and replace with a wet UFH system.

Here are my questions:
1. Can I fit the UFH system to the existing rad pipes but regulates the temp so i don't burn my feet?
2. Are there any systems that integrate into the subfloor to keep the floor height as low as possible?
3. Will they work with the adhesive for the vinyl floor?
4. Am i mental?

I can have a stab at a couple of them... seeing as I have just had wet UFH installed and will be using Karndean
1. I beleive not, you run your UFH through a manifold and separate thermostat, so would need a direct line into boiler
2. No idea, we laid ours in 65mm of screed which is the best system as you then heat the pad
3. Yes, but you need special adhesive
4. No... Maybe

Cheers.

I've found Ambichipboard which looks like it could be installed in as little as 28mm which means i could see a total install height of ~33mm max.

I've done a bit of creative googling and apparently i could do something to connect to existing rad system by introducing a mixer to bring in lower temps but it's all a little above my head for the 10 mins of reading i've done so, if anyone has more info, i'd appreciate it!

Glad to hear i might not be totally mental.
