Firmware Problems on 3750 Switches in a stack

Hope you can help. Is there a way I can down grade the firmware on a C3750 v2 switch 24TS-S v07 to 12.2(35) SE5. I have added this new switch to an existing stack but the FW is not compatable. I believe the answer is to upgrade the rest but I cannot afford any down time as they are used to run a CCTV securiy network 24/7. I have included details below to assist with my problem. Switch 4 is the one with a version miss match. hope you can help Adam

Firmware Problems on 3750 Switches in a stack

Is there a way I can down grade the firmware on a C3750 v2 switch 24TS-S v07 to 12.2(35) SE5.

NO.

The c3750v2 is supported from Cisco IOS Release 12.2(50)SE1 and later.

If downgrade the IOS of the C3750v2 to lower than Cisco IOS Release 12.2(50)SE1 will render the c3750v2 USELESS.

Release Notes for the Catalyst 3750, 3560, and 2960 Switches, Cisco IOS Release 12.2(50)SE and Later
