That would create a low point in the waste where water would lie until the W/M filled the standpipe 6" to let it rise back up and out into the waste outlet. You are effectively creating a long trap. Would it be possible to connect the waste pipe into the downpipe under floor level? i.e, run the standpipe from washing machine to trap below floor, then run waste through the wall (wherever the downpipe is) into the downpipe with a new connection, blanking off the old one if necessary. Another idea might be an extension piece to the washing machine hose (which is pumped) under the floor, then up the wall where the existing stand pipe is. You would need to consult the paperwork with your w/m to see maximum hose length.
Best of luck
