Yes, I can draw you a circuit if you want.
I'd probably use a remote filter take off, to an oil filter, thermostated oil cooler, and on the return line a t-off to the accusump, with a one way valve upstream.
Not massively complex, but does require some additional pipework and fittings.
You also get the bonus of an increase in oil capacity whilst retaining the sump size. Can even use a larger filter etc if you wanted to.
