I think that it is possible because my MTM800 has expanded range to 440MHz :)

Yes, it's possible. But you need depot CPS for 700 series (R6D.533.01 PMVN4160D) to do it.
I'm never seen this CPS in public shares.

Other way is HEX editing of codeplug file. I has been looked MTP700 codeplug in HEX Workshop, but i'm not found where frequency ranges are stored.

It`s very hard to modify dbf file manually, it is some kind of database file... even If You find where frequencies are stored, You`ll won`t be able to correct checksums. I am able to change the bandsplit in Your radio, all I need is codeplug file. Correct Depot CPS for MTP/MTM700 is R7B.398.01 (MR3.1.6).
