Should I make a dual regulator from 2 primary regulators?

[adrichi]

I need to move from a single regulator, 2 port manifold system, to a dual control regulator. Wondering what peoples' experience has been in adding on to a regulator vs buying a new dual reg. I have a backup regulator, so I should only need an additional connection from each reg body, right? One regulator I would use is from 2008, a T749, and the other is a 2016 T742HP. A new dual Taprite is >$105.
I am thinking, remove high pressure gauge#1, remove tank nipple/nut#2, replace with connector nipple. Thanks in advance.

I don’t see why that couldn’t work, I have not done it and I don’t think I’ve ever seen it done but it should work.

It'll work - that's how they gang regs after all
Just have to make sure threading of the nipple is correct. I'm pretty sure Taprite high pressure threads are reverse.
Also, don't go too long or it'll get tippy with a 5 pound cylinder. I have three duals and one of them was built with a too-long nipple which necessitates a tank stand lest it fall right over...

Cheers!
