Has anyone ever seen this?

10-man scout squad + veteran sergeant w/power weapon
Corbulo
Crusader land raider

--or--

Have corbulo next to Mephiston, each leading different squads. Then, use mephiston's quickening on a powerfist veteran sergeant of his honour guard, giving him up to 8 str9 attacks, all rerolled, during the charge. Oh, and everyone else in the two squads will also have +1 attacks that reroll misses on the charge.
