English has no future in the future because English has no future tense at all. English verbs approach tense from two perspectives: before now (past), now and after now (present/nonpast). As such, we can conjugate the verb to eat as follows:
I eat.
I ate.
But there is no way to conjugate the verb for the future, and so we resort to periphrastic constructions to form future aspects, which, for better or for worse, usually infuse other meaning into the sentence:
I will eat (volition).
I shall eat (obligation).
I may eat (possibility/permission).
These all imply future time (and thus form the future aspect), but may infuse undesired meaning into the sentence. Nevertheless, we also have less meaning-rich, albeit more verbose, ways of expressing future time:
I am going to eat.
I am about to eat.
So, although there is no future in the future tense, we can form a future in the future aspect by combining the foregoing constructions:
I will be going to eat.
I will be about to eat.
Both of which sound fine on occasion, but may grate on the ears (eyes) if heard (read) too often, especially in the passive voice: the food will be going to be eaten.
It is also worth noting that the present tense is often used for both present and future time, often making the future aspect seem too verbose where it is still grammatical. Consider the following pairs:
I am going home tomorrow. / I will be going home tomorrow.
He heads out in an hour. / He will head out in an hour.
In each pair, both sentences mean about the same thing and, at least where I live, the average Joe is more likely to say the first. This is merely something to consider, however, and it is not meant to discourage your idea at all.

A clear indication of multiple time frames is not easily accomplished in English (and many other languages). The very concept appears in several variations in Christian liturgical tradition, often expressed in Latin as
This is often translated
There are also statements about status that seem to transcend time, such as
While the implication may suggest past and future roles in addition to the expressed present, these are not explicit. No tense in English unequivocally indicates past, present and future.
