Hello,
The new router won't break the compatibility with the "current" routing system ; so I don't see why it will generate any issue.
More than that, I know that HikaShop did support the crowdfunding made by Hackwar, so we will have some help by the developer of the new router himself 
Regards,

By the way, do not send me private message, use the "contact us" form instead.
