I think you will understand the problem when you analyse a three
component series circuit (your topology), the Loop L, the Loop C and
the Rx input z. (You can ignore radiation resistance, loop loss,
capacitor loss, they are all much less than rx input z so the loops
loss is dominated by the rx input z in your circuit.)

So... if you did this, and you want the loop to give you front end
selectivity, and you want the bandwidth to be xxx which led you to
want the LOADED Q to be 100 or more (whatever), you now know that the
load introduced by the receiver into the series loop you have dictated
needs to be better than () XL/Qloaded or 0.1 ohms (not twenty or
more times that value).

How can you deliver a load impedance to the loop derived from the rx
input circuit and its transmission line that is efficient and less
than 100 milliohms (at the loop)?

Is your single turn series loop idea practical at 60KHz?
