Why do you want a canard sailplane? The canard configuration produces a lower glide ratio and higher sink rate than a conventional tail-in-the-rear design, all else being the same. The canard arrangement makes it unlikely that the main wing will stall and it is cool lookig - but it won't be a 'killer' flying sailplane. One hint is the lack of canard sailplanes flying today. That isn't because no one has thought of them.
What do you want to get from your new plane that you can't get from a proven design?If you want the best flying plane in the area you might reconsider. If you want something that looks cool and flies so so then the canard may do it.
