Is there a Sudden metamagic or SLA feat that...

[RigaMortus2]

allows you to double the range on a spell or SLA?

No, but in complete arcane it states thate you can take improved critical for touch spells an take improved crit for ranged spells
(you have to use 2 feats to get both)

I think (though I could be wrong) that he's referring to the range of the spell as opposed to it's threat range.

Sudden Enlarge doesn't exist officially but it's not exactly a gamebreaker.

Just let it work like all the other Sudden Feats and you'll be fine.

My bad
No official version exists (maybe an incantrix could do this...) but that's not what you're asking for

Time for a house rules Thread

Sudden enlarge is in Miniatures Handbook. It's also a 10th level bonus feat/ability for the warmage(MiniHB and CArc).
