Are you asking for it to be released only after all four chapters are translated? Or are you asking whether its possible for the fully translated story to be posted as soon as the last chapter is released (and translated), which will occur near the end of this month? In either case, while I won't say it's totally impossible, it is highly unlikely you'll get your wish granted.

In the former case, between the impatient demand for something to be released and the time it can take to upload a single chapter, it almost certainly will be released in parts. The only way it would be otherwise would be if a translator has already been working on the other chapters while intentially waiting for all parts to come out before posting anything. Unlikely, considering the demand, and the fact that the translations potentially could be lost while they're simply sitting there taking up space.

In the latter case, it would also require the TL to already be in progress. First off, that would be assuming that someone has already agreed to translate DxD Zero, which I don't know whether there is anyone or not. Second, there's the question of whether the translator has access to the raws yet or not (and there likely will be a delay before the last chapter reaches them). There's also the issue of if they're already in the middle translating something else at the time. It's not important enough that the translator would necessarily drop everything to get this completed and out.
