Making ROMs for one Grand Prime version compatible with another version

I am considering purchasing a Galaxy Grand Prime and the most likely model that I would purchase would be the SM-G530p or SM-G530t. While doing my research on this platform before purchasing I cannot help but notice that the majority of development and ROM releases overwhelmingly support the SM-G530h or SM-G531h.
What exactly is required to get an "H" ROM working on a "T" or "P" model? I am not exactly a noob when it comes to building android ROMs (I am a dev on androidforums.com and very active on freaktab) so your reply doesn't have to be too dumbed down. I am just unfamiliar with this platform. I have a sprint galaxy s4 (SPH-L720), however it seems like the ROM support is better for the various S4 than the various Grand Primes and this hasn't been an issue so far with my s4.
Would it not be possible to take any Grand Prime ROM (ex: an S7 ROM based on 5.1.1 ported for G530H), replace the kernel and supporting files with the 5.1.1 kernel including root for the G530P, flash it to the device, and have a functional ROM?
In general when flashing a custom ROM we won't be flashing the modem or radio partitions, correct? So as long as the android userland version matches the android version that the kernel is built for, and that kernel supports the installed baseband/radio/modem then won't this result in a functioning ROM?
Please let me know if I am incorrect, and if so where is the flaw in my logic!
Cheers and Thanks!!!

thats what i want to know also we need to gather a team and work on the G530P
too many persons buying this phone and being unable to use it globally there must be a way to change the modem or baseband to enable gsm or global features as the other variants of the grand prime series g530/t/h/t1 and others....there must be a way to somehow extract data from each and compile a greate baseband for the g530 to enable call and sms features and ussd features as well cause im sure the g530p is no different from g530t or the other variants in this series as they all have the same msm8916 qualcomm modem but the features are either locked to cdma or gsm/umts
CODERS OUT THERE PLEASE HELP WE NEED YOU!!!!
SUPERCODERS WE NEED YOU ASAP PLEASE HERE US OUT:crying::crying::crying::crying::crying:

Unfortunately, I think, you can't do anything.
You can't install an 530H or 531H ok 530T
To make a 530h ROM fonction on any other model is insanely hard.
I've tried it personally, and everytime I failed.

16gb YES if you read the thread.
However if you fail to read and understand you may brick your phone .
