H cigar did actually offer a spare front c frame for sale for the nano 75 and the board is easy to release plus due to evolv withdrawing their boards from hcigar (amongst others) I'm sure you could retro fit a hcigar board.Personally i think you would be foolish. The DNA chip beats the others hands down mate. you would have to find out the diameters of each board if they dont match its as good as doomed.
