How difficult do you reckon it will be to find statist judges to gladly sign off on “reasonable” restrictions intended to impair, weaken, or defeat piecemeal ...the Second Amendment?
First, fortunately, it's not a matter of a judge "signing off" a restriction. Courts decide cases; they don't give advice to legislatures or approve laws ahead of time. So the way this works, it becomes up to our side to challenge laws that restrict the RKBA.
Now here's where having wise, experienced and skilled lawyers becomes important. We need to pick our fights. We need to find the right fact situations, with the right kinds of plaintiffs in jurisdictions in which we will have access to decent judges. And we need to challenge laws we believe that we will have a good chance of successfully challenging -- laws that are vulnerable to attack on constitutional principles understood by the courts.
So, for example, I think that we'd have a very hard time successfully challenging a "shall issue" CCW law. A court would most likely conclude that such laws present too minor an impediment to the exercise of the RKBA. However, we could reasonably expect to be able to successfully challenge discretionary CCW laws or gun permit laws. It's well established and accepted by courts that it is improper to subject the exercise of a Constitutionally protected right to the discretion of a public official.
And we want to pick our fights carefully so that we have a good chance of winning them. We want favorable opinions and good precedent.
Judges are trained, and it's the culture of the judiciary and the law in general, to take precedent seriously. Judges with agendas may try to weasel around precedent, but they are so conditioned that only the most craven of them will dodge following precedent when it is "on point" and their backs are to the wall. So we want to make good law (i. e., good precedent) where we have the best opportunities to do so.
Going through this exercise successfully will take patience (so we wait for the good cases in the right places), skillful lawyers with good judgment, time and money -- lots of money. So we need to support and fund organizations like the NRA that have the resources to support this type of litigation.

...many advocate for “reasonable” restrictions on guns yet nowhere is this reasonableness defined.
Fortunately, reasonableness isn't the actual, legal standard. The term is suitable for sound bites, but has nothing to do with the standards thus far generally applied to the evaluation of regulation of a Constitutionally protected right.
In general, thus far, courts have subjected regulation of Constitutionally protected rights to strict scrutiny. So arguments that such regulations are permissible will be reviewer closely and harshly.
And, subject to strict scrutiny a regulation of a Constitutionally protected right must:
[1] Serve a compelling state interest -- it wouldn't be enough that it might be a good idea in the eye of the government, it must serve an interest that is very important, basic and essential;
[2] actually serve that interest or at least be well calculated to -- so the state has a burden to demonstrate that it really needs to do this and it really need to do it this way;
[3] be no broader than necessary to serve the compelling state interest; and
[4] not completely obliterate the right -- but still permit its meaningful exercise limited only to the extent necessary to serve the compelling state interest.
So just being "reasonable" isn't enough.
