More toe out will improve your steering turn in, as will some positive caster,
Really ? That is the opposite of my experience , I would go for negative camber to improve turn-in.
The Morgan front suspension will always be heavier than a Mazda MX5 , especially one with power steering, but there are ways to lighten the load which may be what you are looking for.
Firstly I would get the whole front end geometry checked by someone like Cain (Wolf Performance) , if any of the measurements are out he can correct them.
Then try a teflon washer at the base of the mainspring as supplied by GEE. This helps overcome the friction between the mainspring and stub axle.
If that is not enough , try a steering bearing modification by MulFab, needs a new front mainspring to suit.
Lastly (and most expensive) you can get a power steering kit fitted, but I would try the cheaper alternatives first.
