Good brain exerciser. If it were straight cut gears it would work. Most
trannies use helical cut gears. If the reverse gear had a reversed helical
pattern, it would work. But meshing two identical helical pattern gears, going
in the opposite direction would not work. Most of your standard non-syncroed
reverse trannies use straight cut gears for reverse. Your fully syncroed
trannies use helical gears for reverse (first and reverse use the same main
shaft gear).
