That's going to be a toughy! Those two Camel blends were my absolute favorites back in the day and I remember them well, though I haven't encountered any pipe tobacco even remotely close to matching their flavor profiles. There are some similar hookah tobaccos out there, but a finding something with those flavors that you can smoke in a pipe is probably going to require some custom blending.
For Mandarin Mint you're going to need to start with a light menthol RYO cigarette tobacco as a base, something like Golden Harvest Green (which always tasted pretty similar to Camel's menthol to me), then find a really bright and sweet orange flavored pipe tobacco to mix in; though I'm not sure I've ever even seen an orange flavored pipe tobacco before so that may be a challenge to acquire. (Edit: I've not tried it myself so I couldn't say how well it would work, but Rattray's Exotic Passion seems to be a well regarded orange flavored pipe blend.)
Izmir Stinger should be a little easier to recreate, and I'd recommend starting with Sutliff Strawberry Delight as the base. There's not many strawberry flavored pipe tobaccos out there but that's the best I've found. From there you'll want to mix in a bit of a chocolate flavored tobacco, though I don't have much experience with chocolate aromatics so I couldn't recommend a particular one to go with.
I hope that gives you a good starting point though!
