Sounds like you are slowly trying to turn your hand-fed into a stoker.
I completely agree with Rob.Before hacking and cutting up a fairly new boiler,consider a stoker unit,new or used it will last a lifetime.
This is what is installed on my boiler for forced cumbustion draft,fairly simple and parts are avalible,just need to hook up the blower/seloniod unit to the aquastat(i think?) some welding required.
Look at the clayton(USS) stoves,they have a blower hooked up in the ash pan door and have a shutter installed on the blower housing(much more simplier)
