I'm not quite sure I got that correctly...you are paying $39.99/mo for sidekick and a voice plan, or you have sidekick ($20) added to a voice plan? well, either way its no big deal, just switch to 3 day weekend plan ($39.99) and have sidekick added to that. Nights are optional, as they dont come with it but can be added for add'l $9.99/mo with 3 day weekend. Only one catch I can think of which would effect you having both this plan and sidekick is if you were smartaccess, since you can only have pricing plan-wise up to $49.99/mo, sidekick on smartaccess could only be combined with maximum voice plan of $29.99 which is 300 minutes and unl weekends... 🙂
