Swapping from 1.6 to 1.5 rockers isn’t going to move the powerband. The valves will still open at the same time (relative to piston position) they just won’t open as much. When the valves open has more effect on where power is made than total lift.

If it was me I’d swap for a dual plane and see how you like it. If that doesn’t do enough then cam swap. You’ll eat up a set of gaskets if you end up doing a cam swap but that’s a small price to pay for experimentation.
