I have never even attempted this, so i can't definitely say if it is possible or not, but it feels wrong from the start - even if it might work somehow. You need the dump device for immediate access during the boot process and you have only the designated boot disk(s) in this step of the process available. Varying on the rootvg / mounting its filesystems and only then varying on the other VGs comes relatively late (and definitely later than the access to the boot disk is needed).
So, even if you might get this to work (what i doubt) this would be more like a bug in the AIX boot process than a feature and should be corrected.
Btw., "booting from SAN" is not enough information: booting from LUNs managed by a VIO-Server is fundamentally different from booting from NPIV devices. In this case, it doesn't make a difference because for reasons stated above the idea is wrong regardless of which media you boot from - LUNs, local disks, whatever.
I hope this helps.
