If my opinion matters
, Justin, you can operate that club station any way you like.
If your club station has a license/callsign (and I say this because in the US a radio club can have a fully equip'd station without them) - you can use your own callsign, ....or say its used during a contest--- by using some other club member's with a catchier call (ie: a "one by two.")
If you go for the paper QSL's, and the cards come to your club station address, be sure to let the sender know your callsign and name, or else the station manager may have a jolly time (Not ! ) in tracking down who made that contact-- especially if no station log was kept (which is not an FCC requirement.)
In my tender, younger years I delited while on assignments to Kwajelein, (Marshall Islands,) in operating the island's amateur radio club station KX6BU. So did every other transient ham. You could used your stateside call; like "WB6XXX/KX6" - which was not only a tongue twister, it was nothing near as sexy as "KX6BU."
Guess what many many of those visitors used* ?
But unless those visitors stressed their own callsigns and said something like "please QSL via WB6XXX"-- guess what happened to the bushel baskets of cards that arrived every month , addressed simply to "operator John"..... ?
Of course I'm talking here the old dinosaur days before LoTW, and all the Facebookie type e-confirmations or whatever new stuff has arisen to replace the good-bye-gone days of a neat, physical card in the mail---
No one (least of all someone like me) will fault you for how you operate under the conditions you listed.
