Can I tie my 2" shower drain into the 3" toilet drain?

[Jeff S.]

Via a 3x3x2 long sweep heel inlet fitting on its laying on its side, downstream of the shower drain vent take-off, but before the toilet drain take-off? Or does this create an impermissible wet vent section of the toilet trap arm? Basement bathroom. UPC.

Thanks very much.
