What's up LL Forum!

I'm considering doing LL with Mahboubian in the next 2-3 years. My current stats are:
1. Height: 5'6.5" flat footed
2. Wingspan: approximately 5'10.5"
3. Sitting height: approximately 34"
4. Inseam: 30-32 inches (US)

My goal height is: 5'9" flat footed. I always wear sneakers, so I'll effectively be 5'10" to 5'10.5". I plan to lengthen
Femur: 1.25 inches 
Tibia: 1.25 inches

My main concern is that I feel my torso is short + small. I have a short torso and a smaller upper body, so I'm worried that lengthening will further exaggerate the discrepancy and I'll look like I'm walking on stilts. I made a mock-up showing various angles and clothing. Am I still within "normal" range if I lengthen to 2.5 inches?

Note: I know it may seem wasteful to do so little on each segment, but I'm chiefly concerned with three things:
1. Retaining as much of my athleticism as possible (I run a lot, so I'd like equal lengthening to maintain current locomotion)
2. Keeping within "normal proportions"
3. Keeping recovery times as short as possible

Thanks in advance for your thoughts!
