The set

with the midpoints at
   ⟨ 1, 2, 3, 4, 5, ... ⟩

It cannot do so because the reality of the rationals is much larger than
the reality of the naturals.

So yes, you can shift the intervals to midpoints of every finite initial
segment of the sequence 1/1, 1/2, 2/1, 1/3, 2/2, 3/1, 1/4, 2/3, 3/2,
4/1, 1/5, 2/4, 3/3, 4/2, 5/1, 1/6, 2/5, 3/4, 4/3, 5/2, 6/1,  ...

But you must remove them from larger natural numbers. That will never
change.

In the second case, with the changing sets,
who knows?
Perhaps something else could be done,
but not that.

Certainly not. The intervals can neither grow in size nor in multitude.

Infinite sets can correspond to
other infinite sets which,
without much thought about infinity,
would seem to be a different "size".

But they cannot become such sets.
Consider again the two sets of midpoints
⟨ 1, 2, 3, 4, 5, ... ⟩ and
⟨ 1/1, 1/2, 2/1, 1/3, 2/2, ... ⟩
>
They both _are_
And their points correspond
by i/j ↦ n = (i+j-1)(i+j-2)/2+i

But they cannot be completely transformed into each other. That is
prohibited by geometry. It is possible for every finite initial segment
of the above sequence, but not possible to replace all the given
intervals to cover all rational midpoints.

Related rates again, McQuack?
That rationals are about on the order of 2^w,
and, reals are about on the order of 2^w,
is a thing, involved with that
"rationals are countable"
while
"rationals are huge"
and
"reals are uncountable"
while
"reals are constructible".
Of course in mentioning real numbers the context is
to indicate when it means anything else "the complete
ordered field", where that's usually given to
"the real valued", when there are multiple models
of continuous domains here line-reals, field-reals, signal-reals.
So, enumerating rationals is on the order
of exponential, and what's on the order
of exponential also gets right to constructing
the indistinguishable according to 1/n, the 1/2^n.
Then, whence the rational field is constructed,
and numbers are dense in (among) the integers,
the precision of 1/n, is not 1/2^n.
So, book-keeping, and related-rates, and
asymptotics or after concrete mathematics,
then besides the algebra the words the language
of the things after axiomatics, words,
all go together just fine, then though
with neither your "unbounded bounded"
nor the usual "bounded unbounded".
