Is your feature request related to a problem? Please describe.
I want a very extensive end game with the power to store infinite (or at least almost) power, items etc.

Describe the solution you'd like
Being able to craft an creative item in extended crafting, using many late/end game items (singularities, Powah items, ME storage cells, Mekanism ultimate energy cubes, etc) or either with tens/hundreds of regular items (iron, steel, glowstone, redstone, etc).

Describe alternatives you've considered
Having the items received as rewards for very grindy quests/quest lines.

Additional context
I can provide some ideas for the crafting recipes if needed.

Hi. I won't be changing the end of this pack. I've specifically made it achievable / completable for beginners to modded Minecraft and don't think having an extended end game adds to that goal. I'd rather people feel happy to complete it and decide to keep playing or move on as they wish. There are already tons of other packs that do what you're suggesting, and this won't be another one of them. The intent was never to be another one of those packs - It's meant to be mainly around storyline, and not about getting tons of OP creative items, etc. Sorry if this isn't the response you were hoping for, but I'm going to have to say no on this one.
