You may propose, but like many others proposes all over the 
world in all different kinds of forums for so many years, so long as 
there is more than one MTA there will be many holy wars.. but lets 
continue :)

Fact 1 - MailScanner it was written for sendmail :)

I'll go along with that.

Sendmail is only ever as bloated as the features you add in, It disgusts 
me the traps that hte like sof RedHat/Fedora anmd Debian and Novell
put in there packages, it asks for trouble :)

And if i'm not mistaken you are suggesting 2 MTA's? or is it just my lack 
of sleep?

This is weistes way because of his close relationship with that amav... 
why should we change to suite them? when it works fine of 3 other most 
commonly used MTA's?

LOL thats almost as crazy as those that say, use postmix with vpopmail,
but yet you still need qmail installed ;)

Having said that, and the crazy bugger that I am, your idea is not totally 
insane, I have done (because of qmails inability to be secure without 
spending 3 days patching it) a setup as follows which I think is not that 
far from what you are saying...

sendmail/MS ----[                       ]
sendmail/MS ----[qmail no bells whistles]---[NFS to netapp filer]
sendmail/MS ----[                       ]

qmail is used as on the mail delivery box to just collect and store into 
users MailDir leaving sendmail boxes to do the hard yards, it and several 
pop3/webmail servers all mount /home/vpopmail/domains
(all NFS stuff is on separate gbit and uses pvt address space)

Sure it's a cheap, and very very very nasty setup, but it worked last time 
I did it, and worked very very well :)
