It would be cool to see
Rotarycraft
Blood Magic (I know there has been some problems but I put it here anyway)
RFTools
Compact Machines
Project E (doubt this will be added but worth a shot)
Project Blue
Equivalent Exchange 3
Binnie's mods (Extra Bees and Extra Trees)
Soul Shards Reborn
usefulDNS (is this mod even allowed in other packs? unobtainium sword FTW)
Tubestuff (it was in DNS and was fun)
fastcraft (if there is a server side version)
OreSpawn (again, worth a shot)
Morph
Hats
PortalGun
Advanced Solar Panels
I doubt many of these mods will be added (though it would be awesome) because some of them are unbalanced (looking at you project e) but mods like rotarycraft (insanely balanced. it is really hard) and project blue (helps in remaking redpower) are good and balanced.
Thank you for reading
Sincerely,
