from roman catholicism to islam isn't much of a significant change in basic belief. both are based upon blind faith, and share similar moral values. you will get many congratulations from muslims, and cries of disappointment from the catholics. personally i think both choices are false and have the same basic flaws of herd-mentality and lack of tolerance of plurality.
Allah apko bhi hedayat dey. Aamin. If it is decreed for any one to come to the right path, then they will be enlightened like her. It could be you as well. Many hard liners have become Muslims....why not you?
