1st of your idea sounds way to op. Commandos are fine.
Pikes do have some very nice polearms but they don't have hammers (Bring back the old Polehammer!) ,shields/shield skill and good armor. Mar the zwei of pikes with low armor that can throw and halb that dose have some good armor that about as good a market place commandos but cost mills. Commandos also have leg in away it a lot like halb.
Most runs need rg/good slashers (zwei/mar) commandos could be the most needed class in game to make runs work.
Only class i still think may need a look at is Aventurier but it has some speed i guess that could make it fun.
