Combine decomposed forecast with a Holt-winter forecast

I just want to know, can i combine a decomposed forecast with any other non-decomposed forecast like holt-winter and is there any reference to someone who did something like this before?

I don't see a problem with it, but i would like an opinion from someone else.

The new combined forecast calculation for a certain time period say (t) would look like this:

Comb_Forecast = max( Holt_winter_Fcst, Holt_winter_Fcst*0.5 + Decomposed_Fcst*0.5 )
