can four flanged D11 trixbrix wheels be fitted on a 880011 poweredup train motor? Which trixbrix rod would then be needed? 21344 Sapphire Star motorized by a single 88013 poweredup motor (StijnD MOC-165803) is largely underpowered even on R88 tracks, so do you think that the above suggestion would improve performance❓ (I donot mind changing Whyte notation to 4-4-0 or overall appearance...)
