Another thing, you will need to lengthen the distance between your primary and spider/focuser/imagining plane by an equivalent distance as from the secondary across to your imaging plane, possibly somewhere around 6-12" depending on the size of your primary and the focal plane point.

I suppose it all comes down to, what are you going to gain by doing it?

Seems like a lot of work and cost, for the gains you "might" achieve.
