extended eye relief or scope mount 4 trijicon MKIII

Does anyone have a extended scope mount or screw on eye relief for the Trijicon MKIII scopes? I have long arms and have mounted the scope rearward about 1" with the Daniel Defense extended 1/2" riser, but it still is not enough. Would be nice if someone made a magnified screw on eyepiece to accept the stock or even a different shutter to enable a ar stock to be fully extended.

If not, then maybe i should design it and sell it for $150.00 or so plus..
