ok this is how you could do it

1. You need to have 2 compact flash cards and a compact flash --> memory stick duo convertor or 2 old memory sticks and a memory stick --> memorystick duo convertor.
2. Put the 2.6 upgrade on your first memory card (compact flash or memory stick)
3. put the 1.5 upgrade on the second
4. plug in your memory stick duo convertor.
5. run the 2.6 upgrade without a AC adaptor in.
6. click start on the upgrade and when it gives the AC adaptor error take you memory card out and replace it with the second card. WARNING: DO NOT UNPLUG THE MEMORY STICK DUO ADAPTOR!
7. put the AC adaptor back in and click start.
8. Then it should upgrade to "1.5"
GOOD LUCK
THIS HAS NOT BEEN TESTED!!!!

wouldnt it say memory card has been taken out and wouldnt work?

however might work with that hard drive which converts and uses basically all type of media

so that it is always in the psp tricking the psp into thinking the memory card hasnt been removed i think

if we cold find some way of swaping without losing a connection to the psp this could work!
