Absolutely! A common tactic for me when I'm doing assaults or advances is to not buy a truck company for the Pioniers and just pile them onto the StuG's to ride them until just before the point of contact. I'll usually dismount and sweep ahead on the road or path with the engineers about where I estimate to be running into mine belts or ambushes.
For assaults I tend to go Pioniers in the lead, StuG's right with them or right behind them, and a company of SS-Panzergrenadiers or regular Grenadiers bringing up the rear along with a Panzer company. If I'm feeling frisky sometimes I'll pick up some of those engineering tanks and lead with those too
The ISU/SU series with the enclosed fighting compartments are very very good at this, much better than even the StuH 42 because of the larger gun. Especially with experienced crew, I find that enemy defenses practically vaporize if you give them the time to work over an area properly and keep the engineers looking around.
