Really sounds like you just need something with a little lower saddle height than a dual sport/adv bike (which are admittedly rather high).
The BMW 650's are about 2-3 inches lower than your V-strom, if you're still aiming for something more adv-ish with a conventional posture.
A Triumph Bonneville is about 4 inches lower, still conventional posture.
No need to go cruiser, or snowmobile.
