Planning for 2011 outdoor season

Do you think it would be ok to end my SPP for example on 14th of May and then compete and keep weights at maintenance till beggining of June. Then when I have one week without any races (2 weeks from my nationals where I want to peak) I would increase the volume of sprints and do some max weight tests. That would mean that I raise overall volume and therefore intensity in order to get sth to taper off for my nationals.
