Quick Question - How to event on multiple clocks rising edges?

You shouldn't AND the clocks, because that will give glitches.

You could use the falling edge of the fast clock to detect the start of the slow clock. And either use the falling fast clock to clock your state machine, or start the state machine running on the rising clock with this pulse you just generated. In the latter case you have doubled the speed requirement, so there will be an upper limit on the fast clock.
