In order to keep the 1:1 ration, this should be as below I think (assuming 
the "149 mm" to be correct and just calculating the rest).

75 mm   EF 50mm f/2.5 Compact Macro
149 mm  EF 100mm f/2.8 Macro
149 mm  EF 100mm f/2.8 Macro USM
268 mm  EF 180mm f/3.5L Macro USM

At least this seems reasonable to me...
