Reality of shadow spells and Limited Wish

[Alleran]

Brief introduction, I'm building a caster who specialises in Illusion, but no Shadowcraft Mage or Killer Gnome shenanigans (not allowed). There's the +20% for damage spells via Enhanced Shadow Reality and the School Mastery Illusion (+10%), a total of +30% for damage or +10% for everything else. Would the Playground consider using a Limited Wish spell to gain +10% reality to shadow spells (either on an encounter basis, or a turn-by-turn one) to be in line with this element of Limited Wish:

"Produce any other effect whose power level is in line with the above effects, such as a single creature automatically hitting on its next attack or taking a -7 penalty on its next saving throw."

Essentially, would a temporary +10% reality seem to be a fair use of the spell? I'm primarily gauging a general opinion from others at this point in playing with the build, so "talk to the GM" isn't really a response that I'm looking for at this point.

I might allow it, but only for the next shadow spell you cast, not the entire encounter. That would be in line with a one-time buff to an attack roll or saving throw, which the spell can do.
