depending on your modelnumber you can already do that.
creating new code plug can e done with depot/lab cps but that's not legal offcourse ;-)

would not advise to set maximum frequency to 440 and it will effect the sensitivity of the radio, after 435mhz it goes deaf

i've seen the signal higher than 435 MHz and it totally unstable, looks similar to a hopping gsm signal, but much slower^^. on 435 and lower, it has a nice and strong signal. so 435-440 should work on the 440-470 radios.
luckily our ham-repeater is on 431

How can you be using an mth800 on a ham repeater? Lol

Tetra signal has DQPSK modulation that can't be passed via HAM FM repeater. You need DMO repeater for do it.

we have a ******** CM5000 in dmo repeater mode for ham radio here

That's something that will never happen in the uk

you could host a tetra dmo-repeater yourself, if you have a ham license. it's that easy :)
