AxROM is actually incredibly based. Rare used it. Check out Cobra Triangle; it's amazing for 8dir scrolling.

That's one way to do it, Rare did this, but it's not even necessary. You could do it with an NROM. Set vertical mirroring, use one nametable for the gameboard, and have one status bar drawn at the top of the other nametable. Set sprite 0 near the bottom, when it hits, set the ADDR pointer to the top of the "other" nametable, set X and Y scroll to register to 0, and there you have it. You can load in vertically scrolling graphics as necessary in the "masked" region that the status bar covers.
It's not (relatively) difficult to have one status bar, but two can get messy. Looking at that screenshot, the top bar consists of the Title of the game and the score. There would be plenty of room work the score, lives, and level into a single bottom status bar; ditch the top one and the title of the game. That's how i would do it anyway.

It's honestly not a bad idea. Use one nametable for the playfield and another for the status bar. Rare did all kinds of awesome shit with this setup.
