Bishop has been sidelined with a foot injury of late but the 30-year-old resumed training with Kevin Blackwell's squad this week, while on-loan Leicester forward Hopper was ineligible for last weekend's 1-1 draw with Southend in the FA Cup.
The pair's availability may mean Lenell John-Lewis having to settle for a place on the bench having made a surprise appearance in the starting XI following a knee problem against the Shrimpers.
Ben Parker joined the Shakers on non-contract terms on Thursday and is expected to be available to make his debut but, as of Friday, the club were still waiting on paperwork to confirm the former Leeds defender's eligibility.
Striker David Healy (calf) remains on the sidelines along with long-term injury victim Phil Picken (knee).
