I agree with Stan, not a good idea, and also a waste of time. Do you have check scrubs and extended offline smart tests scheduled for these drives periodically?

I think you should put in a replacement drive for sda (#6) and get it rebuilding, as sde seems rather tenuous, before you decide to remove sde.
You should find out why it's slow 'smartctl -A /dev/sde' might reveal this now, which you can issue even while the reshape is occurring - the command just polls for existing smart attribute values for the drive. If it's the same model disk, connected the same way, as all the other drives, I'd get rid of it.
