How much is too much trail?

I'm refurbing an old Cannondale ST (touring) frame, but do not have the original fork.
The Frame is 25" size, and has a 72° head tube angle.

Dimensions for the original, fork 1 and fork 2 are:

Fork.......Axle to crown...Rake....Trail
Original.....385mm..........55mm...55mm
Fork !.......403mm..........50mm...58mm
Fork 2.......400mm.........44mm....64mm

Question is: are either of these acceptable, or will the increase in trail make the bike demonstrate unsatisfactory handling characteristics for loaded touring??
I cannot afford a custom fork, and I have not as of yet located an original.
Can fork blades be "adjusted" safely to achieve the original rake, or am I worrying too much about it?
