I remember doing this, both ways, some time ago. Non-Schengen to Schengen is clumsy, as you need to go through everything. Passport control, customs, and security again.
The only thing you can speed up is 2E to 2D. I remember walking, and it took me 15 minutes, give or take.
On the way back, 2D to 2E was easy. Walk inside the secure area, no security check, and passport control only to exit Schengen.
