Help please!

I've got a Stronglight 93 drive side crankarm mounted on a frame and I can not get the crankarm dustcap removed. The cap has a stripped allen hole in the center (came to me that way, really). So far I've tried:

Penetrating oil heat on the cap but not on the aluminum arm punch with a hammer to try and drive cap to turn which ended up actually tearing the steel cap....

.... all to no avail.

Any ideas, tips, techniques or magical spells I can use to get this very stubbern cap off?

Thanks in advance to all that reply.
