Homebrew PCBs

Hi all,

Didn't see any discussion on this topic in past posts, so I thought 
I'd throw this out to the group...

I am trying to reproduce a circuit board for a very old arcade game 
from 1975.  Its an old style pitch and bat game, so the electronics 
are fairly simple, but the board is huge (approx 13x19") with about 
100 TTL Logic chips and various resistors/capactors.  Double 
sided...  This board is no longer available and I have not been able 
to locate a board for quite some time...  I was able to borrow a 
board from a fellow collector, but it is only on-loan.  I also have 
the schematics...

My question to the group:  Does this sound like a resonable process 
to reproduce this board:

1) Remove all components from board
2) Scan in both sides (double sided board)
3) Touch up artwork and output to transfer paper
4) Transfer images to copper clad board
5) Etch, drill, populate...

Is this the process most of you would follow to reproduce a board?  
Or am I missing an easier process?  I actually thought about re-
designing the board a little smaller, but I cannot afford the cost of 
an auto-routing software package to do a board of that size.

Any thoughts or suggestions?
Thanks!

Tony
