There will be a number of issues to contend with if you wish to go for the same size tyres front and back.
Currently, the bike as a 5.5inch by 17inch rim on the back for the 180 section, and a 3.0inch by 18inch on the front for the 110 section. There is no safe way of fitting a 180 to the existing front rim (especially as I doubt that a 180 section is available in 18inch diameter - maybe ask a Honda RC30 rider for options!)
So, you could go to a 17 by 5.5 inch rim on the front. This will require the following to be determined:
1. will the tyre physically fit between the fork legs? (measure between available width under the mudguard) Unless there is at least 40mm clearance either side of the stock tyre, the answer will be no - or 30mm if you go to a 160 section)
2. to match the wheel style front to rear, you will need to go to either bespoke wire-rims on custom hubs easily doable, if pricy) or modify (lots of machining etc) a std Scrambler rear wheel to fit between the fork lowers, and achieve the correct disc mounting face at the correct alignment with the calliper. Of course, none of this may be possible without a lot of measuring, head scratching, designing, money and machine-shop time) My gut feel is that this is a technological dead-end.
Another option would be to make the above issues easier to resolve by commissioning some custom yokes with a much wider spacing between fork centres. This would help ease all the interface issues / conflicts, although the whole system will still need designing and machining up. Of course, wider yokes may have interface issues on full lock with various existing frame / cowling elements on the bike, and you will need new spindles and mudguards made up too...
So, in summary, there is not an easy, safe, DIY fix i'm afraid, however, anything can be achieved, given enough effort, know-how and of course money - this would be a good commission for your local custom / bobber / hipster / race bike builder.
I'm sorry if this rather dampens your enthusiasm - the only reason I cast such a long list or challenges is because I have had to tackle them all on my own one-off builds in the past, and learnt the hard (and expensive) way!
p.s., the handling may be somewhat compromised too....
