I cannot see taking a recert checkride in the times you suggested. That would logistically be tough with our resources. A voluntary yearly recert to maintain your rating may be the way to go.
Those of our pilots whom just fly only FMC, GPS routings miss out on all the benefits of using the FS program to the fullest. I mean not using the NAV radios, or compass, etc..
We were looking into "certifying" different aspects of flight with different aircraft. This would not be related to the RETRO checkride. We have nothing specific, it was just discussion.
The idea behind our graduated checkrides is to get each one of us to utilize the real world procedures and hopefully use them each time we "fly". They get more invovled each time one takes a checkride.
As the ATR is phased out from the AAL real world, things need to start changing in the way we do business. So if one is interested, seriously, to take more certifications checkrides, something could be done.
Of course as always if one brings up an idea, they have to fall in line to help out.

Thanks.
