According to OT2, going to 70lbs would put you at 266 FPS and your KE to 78.49 and momentum at 0.591 so it will go up.
The question will be if you want to put more into that particular bow. Just buying new limbs won't be the entire cost - you will still need to swap them out and that will be some bowsmithing costs unless you have your own bowpress and know how to do it yourself.
If for example, you bought a used 2016 Mathews Halon 6 (certainly more expensive) you could be shooting 294FPS with the same draw length and 70lbs you would be shooting with the hornet, but your KE would be 96.06 Ft-Lbs and momentum up to 0.653 so it would be a huge jump. In fact, that same Halon 6 would be putting out a faster arrow with more KE and momentum at 56 lbs draw weight than your Parker at 70 lbs. That translates into fewer bad shots if you are struggling with the additional weight, although I think that shows more in practice where fatigue is a factor compared to an actual hunt where you are only shooting a few arrows per day.
For mostly US hunting, I don't see much need for more power on your existing bow. If you wanted more power, I would look at getting a more efficient bow rather than cranking up the draw weight unless you plan to always shoot a 70lb bow and maintain that muscle year round. My suggestion would be that if you are comfortable with your accuracy, don't change it. Maybe run a fixed 2-blade broadhead for the bigger animals to assist in penetration and use the fixed 3-blade ones for smaller perhaps, but you should be good with what you have as long as you are spot on with the arrows. If I changed anything on your rig, it would be to add 50 grains to arrow weight but it wouldn't be necessary as much as just some extra insurance. That would still require re-sighting in your bow, but I am certainly sold on heavier arrows. Perhaps you could add 25 grains to your arrows (don't know what BH's you are using) and taking the string silencers off. That might offset the speed loss and just give you more impact and momentum with only a slight change in string noise that could be largely offset by the extra arrow weight. If your string silencers are easy to remove and put back on and you can get a heavier field point, it would be easy to try out.
