Ian's answers are all valid and most are better long term solutions,
however in the spirit of fast and dirty...

Another option that is fast and easy to achieve if a pain to do every time is:

1) submit all jobs on hold from cluster A and cluster B with priority 0

2) edit the job priorities of both clusters so that even or odd
numbered jobs have a higher priority

3) release your jobs

this should cause them to be interleaved.

This will not work well with other jobs in the queue (you would have
to recurse the above instructions and would eventually run out of
priority divisions as currently you have only -20 -> +20)

That said this is going to get the simple case working immediately
