Certainly.
The bill in question specifies in its preamble that it is invoking the unilateral federal amendment procedure under section 44 of the Constitution, which solely requires the adoption of an ordinary law by Parliament for matters in relation to the House of Commons.
I did a bit of research on this point and I would draw the subcommittee's attention to the Fair Representation Act, which was given royal assent in 2011. It amended the same provision of the Constitution that Bill C-246 would amend. This was done by way of the section 44 unilateral federal amendment procedure under the Constitution, so there is a precedent.
The subcommittee is not bound by that precedent, but it could be instructive to the subcommittee. The role of the subcommittee is really to apply the four criteria, one of which is whether the bill is clearly unconstitutional. Perhaps there's an argument to be made here that the bill in question does not meet that high bar, but it would be up to the subcommittee to determine.
