A follow-up on the RRIFing question above, from the age of 65 to 71 it would be nice to model taking out more from existing RRIFs to see the impact on your future legacy including potential government clawbacks. 

Would this be best done by increasing expenses, however, the issue is that this money wouldn't be spent but used to add to TFSA room and or non-registered accounts. Is there any way to do this (i.e., increase the $ or % coming out of registered accounts before age 71 (via a date range) where the amount after taxes is placed in TFSA and/or non-registered account based on available room and appropriate taxes?
