Actualy, just about every proposal made so far has already passed muster.
Actually not a single one has.

With regard to state gun laws, for instance, a recent Second Circuit decision upheld New York’s law limiting concealed carry licenses to persons showing “proper cause.”[10] In Hightower v. Boston, the First Circuit rejected a constitutional challenge to Massachusetts provisions governing revocation of concealed-carry permits.[11] Another decision, by the Ninth Circuit, affirmed the constitutionality of a California county ordinance restricting firearms possession on county property.[12] Yet another, by the Eleventh Circuit, upheld a Georgia law banning arms-bearing in houses of worship.[13]
Most interestingly, last year the D.C. Circuit deemed some handgun registration,[14] assault-weapons bans,[15] and prohibitions on “high-capacity” magazines[16] to be constitutional.
Many federal laws have also survived recent Second Amendment challenges. For instance, federal circuit courts have affirmed federal bans on juvenile gun ownership[17] and handgun sales to persons under 21.[18] Other decisions have upheld federal restrictions on interstate firearms transportation[19] and gun possession in national parks.[20] Still others have deemed possession of pipe bombs[21] and unmarked firearms[22] to be unprotected by the Second Amendment.
No less than five circuit courts have affirmed federal restrictions on machine-gun ownership.[23]
Another body of case law has affirmed federal bans on gun possession by various categories of people. At least ten circuits, for instance, have upheld a federal provision banning firearms possession by convicted felons.[24] Five have affirmed a similar ban for those convicted of a misdemeanor domestic violence offense.[25] Four have upheld such a ban for persons convicted of drug-possession offenses.[26] Three circuits have upheld a prohibition on gun possession by those subject to a restraining order;[27] another set of three has also affirmed such a ban on illegal alien gun possession.[28] Finally, two circuits have rejected constitutional challenges to similar ban for drug traffickers.[29]
