Okay this might sound strange, but I was considering being a Kobold summoner, and I was wondering what you all thought of this. At 18th level, taking the Greater Aspect ability and becoming a Large sized Kobold. I know it is probably against RAI to do it, but as far as I can see, it isn't against RAW unless there is some errata I've never seen. I'm sure my question would apply to all small summoners considering this.
So the question is this: since the statistic adjustments are based on a medium sized eidolon being upgraded to a large, would you...
a) need to apply the reverse of the small eidolon adjustments before you made the large adjustments?
b) apply the adjustments straight up and make the kobold large?
c) apply the adjustments and make the kobold medium?
d) other?
