ACW- more protracted Confederate raids into North

How could Confederate agents in Canada have conducted greater and more effective raids into Northern soil during the course of the ACW, similar to but of a greater scale than on St Albans, Vermont, in Oct 1864 ? Further, how could Confederate raiders from Kentucky and Missouri have conducted more effective raids into Indiana, Illinois, Kansas and Ohio, similar to the burning and sacking of Lawrence in 1863, and possibly facilitated co-operation with the Copperheads in order to seriously threaten Union interests in the Midwest (similarly to the 'Northwest Confederacy' post earlier) ?
 
ot the north per se' but Stand Watie could rouse comanche/apache setiment in a drive west towards California. he would have to not be a confederate general, but a devoted anti union indian agitator which I don't see him becoming. However it would not be outside the realm of possibilty so I offer it
