Strange situation with interior sillcock

[Yeedle]

For some reason, the previous homeowner installed a sillcock on the inside wall of the garage to hook up a hose. The interior sillcock is a sweat connection and the connection is in the plaster wall so not easy to remove without destroying the wall. I would like a sillcock on the outside of the garage and since I don't have any other easily accessible plumbing nearby I was thinking of the following:
- Connect GHT to NTP adapter on interior sillcock
- Connect a NTP to barb adapter for PEX
- Run the PEX to a frost free sillcock on the outside of the house (connection made in the garage about a foot way from interior sillcock)

I know this is a strange setup but wanted to know if there is anything wrong with it with going from sillcock to PEX. I don't care how it looks, just want sillcock on the outside. This basically converts the interior sillcock into a shut off valve which I plan to just leave open and only use the exterior frost free sillcock to turn water on and off.
