You can tiller a bow beyond your own drawlength. Just use a tiller tree to pull it further than you could draw yourself. But you can also pull a bow yourself to the drawlength you can achieve yourself. There's no difference in pulling a left handed or a right handed bow. The only difference is the side the arrow passes the handle. Heck, you could even shoot a bow with some arrows on the 'wrong' side of the handle! Test shooting the 32" drawlength would be impossible for you, so your might ask assistance to someone who can actually draw 32". Although you may be able to fire some test shots at 28½" yourself, it would be better to also test shoot it at full draw, just to make sure the bow behaves good in terms of handshock and smoothness of draw.
So, I don't see a problem for you. I think you're making it more complicated than it actually is...the bow doesn't know if her archer is left or right handed!
