Can you add a crowd funding apsect to your fundraising plugin

Like http://www.ignitiondeck.com/ & rockethub.com where you can still get the funds even if you don't reach your targets or also have do all or nothing option. Basically just give options to the site owner. Some of the plugins out there just don't work with all themes & only allow all or nothing which is restrictive like kickstarter prefer to have the both options like rockethub.com.
