Would that be a regular bmx type rim?

Its good that you're aware of the need to have confidence in the shock absorber/spring mounting. That short shock is pressing into the center of the long tubes that are your stays, however. The stays will be subject to a repetitive flexing for which they aren't designed.
A much better point of attachment would be in a way that transfers the force to the junction of the top tube/seat tube/rear stays. A longer motorcycle or moped shock would span that distance, have better damping, and most have a five position spring preload adjustment. They also come in about any length you'd need.
