Yes, it will since it supports DiSEqC 1.2. The 80cm dish is the minimum size for a monbloc LNB so you should be OK. You may find a satellite finder helpful when aligning your dish because the focus may not be the same when you replace your LNB. You want the main on Hotbird and the second focused on the Astra. Set antennae 1 to Hotbird and 2 to Astra. You can check each by covering the LNBs in turn with a wet cloth. Happy viewing.
