Hi, That is a quite tight spot that you are in. You can register for GUJCET if you meet the eligibility criteria. But the examination schedule as in the timings haven't been released yet. If your CMSE exam is during the morning and GUJCET is during the afternoon and you can make it on time to the exam hall, it is a good chance. However, if both of the exams are either during the morning or evening, or even if the timings clash and you can't make it, your efforts will be in vain. Technically, you are eligible for writing the exams that you are eligible for. But it's just that the timings shouldn't clash.
