Oh well, that's an easy solution, but shift out to where?

Unless the LED modules have a shift register that accept serial (data/clock)
and with a "borrow" output allowing to cascade several modules.

You can also use a fpga logically programmed to convert 8 bits (the high
order counter byte) into a 5x6 matrix... or 3x10... or something else, and
never needing to use a microcontroller, oscillator, nothing else.
