Supplementing fin with dut?

[25 going on 65]

Finasteride's half life is about 6 hours. Dutasteride's is about 5 weeks. Instead of switching from fin to dut, has anyone considered continuing their fin regimen but "supplementing" it by taking an occasional dose of dutasteride? Like once a week, once every few weeks, or whatever?
I don't know if this would reduce the likelihood or severity of short and long term side effects, but given the suppression of the type I ar enzyme with dut (which does not happen with fin, at least not significantly), I've just been pondering methods that might reduce the risk for those of us who might go on the drug.
