I rather think anything worth aerobatting has a tailwheel anyway.
Get yourself into the Decathlon and complete your basic flying training, ie. the ability to operate aircraft with conventional undercarriage.
As stated above it would be killing two birds with one stone.

10 hours for a tailwheel conversion is, as can be read from your post, double what it takes (for most students). How 'bout you name and shame the club who so shamelessly fleeces their customers in this way?
I have a friend who offers a combined tailwheel/aeros course for which the lesson plan is 10 hours. The aeros bit is quite thorough including flat spins, Muller recovery, and inverted spin.
