If you have the budget yes the return pump makes sense, it's just these pumps need loads of power compared to a small powerhead.
On my inverter system the return last maximum 15 minutes, on the powerhead 2 hours.
Cost to upgrade R4000.00 and that will give my return pump another 1 hour usage.
So if budget ain't a issue, have the whole tank on an invertor system, for probably around R100K
