Well i have tried with succes i might add the idea is not really a chaneel dash but a atlantic wall in form of a German navy that is easilly reinforced, making it lenghty procces for UK/US to hit germany.
Let me explain: (works best with a axis bid of 8 but can do without bid or bid to libya (2 units) way.)
G1 buy: 1 carrier, 1 IC, 3 inf
IC goes to Western Europe
carrier to SZ5.
Normal “pull back” to Eastern Europe (if russia hasn´t been silly).
Med fleet take gibraltar, if bid of 8 you can do 1 of two things, either a trn in med, that attacks Egypt (with 2 figs on the dest) or a sub in SZ7 atacking the uk fleet, with 2 subs 1 fig, 1 bmb. (very good)
on G2 you move SZ5 fleet to SZ north of france lands 2 fig on carrier, builds another carrier lands 2 fig there as well (or att the afctory moving them on depends on rules).
Other than that you might wanna consider another sub, but ned to get more ground troops so usually you skip that.
If able you merge the med fkleet with SZ5 fleet, if blocked with a single or small nr of ships kill them with A and unite anyway in non combat, if closed by force hit it with ships + af, making a counter attack expensive if you have your SZ5 fleet intact.
Objective hold US/uk occupied with building ships, hit voulnerable ships if able, take Brazil if able (and nothing threths you).
Reinforce russian front , but objective is to hold untill Japan arrieves and then make a joint push, around round 6-7, might be able to hit moscow at 9-10 and may be able to hold Allies away from Europe atleat into round 8, more if you managed to hit something,. or get a succesfull suicide attack in.
