It might be possible to come up with a method to mount all the keys in a
indirect map on first access but that sounds like it would be more
difficult than it's worth.

Do you really need to mount these separately?

Could you use a direct mount map instead?
You could do this by using the following:

in the master map (possibly /etc/auto.master):
/-	/etc/auto.direct.homes

and /etc/auto.direct.homes could contain:
/home	oscar:/home

This way there is only one mount not many and it will always make all
home directories available on first access.
