shift boot block and main block

Hey,
i build a mod for my notebook (dell vostro 3350) at the moment.
inserted different modules, but now the space of the main block is exhausted.
so my idea is the following:
main block: | Bytes Free : 00C5F0 ( 49 KB) Bytes Used : 1C3A10 (1806 KB) |
boot block: | Bytes Free : 0266E8 (153 KB) Bytes Used : 039918 (230 KB) |
Is it possible to edit the boot block (make it smaller) and add the gained space to main block? :slight_smile:

Kind Regards
