I wouldn't do it unless I was adding a late M42 with a J type OD. I've got the long stick in my Amazon Wagon along with a D type OD. I've also got an early type P1800 extension that I could fit. It even has an extension from a Ruddspeed car to bring the gear knob up from between the seat squabs. The later one sits higher and having driven an Amazon with one of the later sticks and found it a rather mechanical change lacking in the sweetness of the long stick. I also don't want to cut my perfect rubber front mat!!!
