I think it's NOT good (in terms of 'reprap philosophy'), the philosophy of reprap was to use vitamins and combine them with printed parts, and not completely replace the vitamins with printed parts. This is very inefficient and material use and energy cost will be much higher.
Besides that I do like the idea, and with the corner connectors on both of the top connections being a corner, it looks as if it can be rigid. But I wouldn't trust it to be more rigid than an i2.
