The issue with any other board is that the boards aren't going to have all the same ports and compatibility so you'd have to have potentially two largely separate forks of the cores and accessories which would be tough in a relatively small community like the Mister. For example your board doesn't have the large pin headers used by basically every Mister accessory so at a minimum you'd need an adaptor to go from some other port on your board to the pinouts that the mister ecosystem is built on.
