DO I need to change lineset

I have a Goodman CAPF3743C6DB coil as part of our 3 ton, 18 seer, 2 stage A/C system. The specs say it can be used for A/C or heat pump applications. Can I simply replace the condenser with an appropriately sized heat pump + TxV + incidentals and keep the coil? The lineset is 3/4" and runs 40' straight line horizontal, 90 bend, 5' horizontal then turns to 3' vertical. Does the lineset need to be replaced? Upsized to 7/8" I was told the lineset "might" be able to be saved. IT is R410.

Thanks.
