I dont think theres anything wrong wth this request although i personally dont think a new arena is needed.
It could be done with a new map if you have a squad willing to practice this way.In fact as long as you have enough friends to play together you can set up this very thing on H2H.
There is a map of germany which has 25k or so airstarts right now. I have played it and the airstart does drop you in with no engines or speed but it still works.
Basically TOD will do this bomber/escort constant playing that you describe here.There appears there will be constant missionsrunning in AI at regular intervals which we as players can choose to join or defend against. We will use avatars or different characters, to play as the various types of pilot. Be you an Axis fighter pilot intercepting the bombers ('dicke auto' is name given to bombers by the Luftwaffe pilots Bendover) or maybe a special Jabo intruder pilot using 190s or bombers to attack the allied rear supplies or maybe a B17 pilot on his tour of 30 or so missions or Fighter pilot charged with defending the lumbering boxes of b17s.
This is what a lot of us want to see. Targets that we wont have to spend months searching for like large bomber streams.
If HTC could make a sort of offline practice feature?
well in a way they have already.I/you can go online(in H2H) or offline and load up the germany map, then i/you can drop in at 25k and practice bombing all day long. I/You could restrict the types of planes which can up to defend, change hardness of targets and all sorts of things like wind and radar settings.
Ok so you dont have the AI bombers but like i said you could set up H2H and get squadmates to join and perform the various tasks like flying bombers in formation and defending in fighters.
Why some others have jumped on your back for asking for a such a simple thing, which i agree would make an enjoyable sort of bomber practice arena, I cant understand

but I think when TOD arrives it might well be so good we wont want to be airdropped to save time but rather fly the entire trip with the slow taxying out among a hundred(ok maybe 20 or 30

) other bombers, the fully loaded tricky launches, flight to and from targets with its AI or Human defenders appearing and making attacks on bombers, hoping to find and kill the human players. Little things that will make it great, like not flying your bomber properly in the AI formations making you an obvious human bomber and making any non AI enemy nearby pick you out because of it!!, its VERY similar to how the LW pilots used to pick out the new green crews by attacking any bomber that had trouble maintaining position in the bomber boxes, be it going too fast too slow or just having trouble staying steady.('Combat crew' by John Comer).Falling out of the boxes was at some points in the war almost certain destruction by hordes of heavily armed larger fighters waiting to catch just such a slow lone bomber without the boxes protection.
Its going to be great

hehe wait for it then if its not enough have another crack at the ' bomber practice arena'. Hmmm BPA has a nice ring to it
