Yes. As people have commented before, good luck, because you will
need it!

So, how do tree seeds normally spread? In the case of hazel, oak, etc,
obviously birds and squirrels, and they are the right size to be
attractive to these creatures. Alder seeds seem too small.

Birch is related, and they are distributed by the wind for quite
a long way, and can be a real pain. Naturally, that selects against
becoming large. I don't know about alder.

Has it ever dawned on you that over many thousand of years of
gathering anything that was edible someone during mankinds evolution
would have found Alder seed and some selection would have taken place
if it was of any food value.

Yes. That's irrelevant. Some plants have been chosen for agriculture
and others haven't and, in many cases it's completely unclear why.

Goosefoot is edible, both in leaf and seed, and was eaten by the
neolithic peoples as seed at least. Now, how many cultivated forms
of that do you know?

Some widely-grown plants, including hazel and walnut, are essentially
the same as the wild forms. A little selection has taken place, but
not enough to make much of a change.

And I could go on.

Well, I toyed with the idea of sedges. They have heads very like
grasses. Maize is almost unique among the grasses in having heads at
intervals up the stem, which makes it possible to have a plant which
produces a lot, but isn't bent over by all that weight at the top.
That comes naturally with sedges. Just to make the "right" choice is
huge task. I have chosen on a "hunch". I am impressed by the tree's
vigour.
