No, sorry. Riot will not remove low priority queues for any reason. If you are experiencing connection issues you need to try your best to get them fixed, and otherwise not play when there could be interruptions. If you rarely have any issues then your leaver status will diminish and you can get low or even no penalty for the occasional leave.
If you need help solving a connection issue, please refer to the Connection Troubleshooting Guide, and post on the Help & Support board if you need assistance.
